Application filed June 25, 1921.A Serial No.,480,435.

To @ZZ iti/2mny t 72mg/ Conor/rn `Re it known that I, Cmns D. Mirna, a citi- Zen of the United States, residing,r at West Hoboken. in the county ot' vHudson and State 5 ot New Jersey, have invented a new and useful Flush Valve, of wliiclithe following is a specification. i i

This invention relates to flush valves used in flushing` urinals; and has tor itsrspeoial object to provide a device oi thiskind especially adapted'it'or use on board ships where salt water is used for thev flushing urinals, toilet-s, etc. j

the several urinals, or other places, on board a ship. Sutlieient pressure is kept on this water so it will performV the Vfunction of flushing', when desired.

invention to provide a flush valvethat'will Ybe regulated in part by a separate fluid 25 thereby leavingr the main passa'aeways sutliciently large that salt water mayreadily pass therethrough without danger or clogging', or getting inoperative.;

The invention is illustrated in the acfV 30 ooinpanyingV drawing, in whichf f Fig'. 1, is a central, .vertical section of flush valve constructed in accordance with' -my invention-the portions oiu the-connect- Vinfrpipes being shown in full lines; and,

Fig. 2, is a similar view, showing workingl parts inV a dil-ferent position, and

Fig. 3, is a sectional view, on an enlarged scale, showing` how the pilot valve operatesl to regulatethev ilow ot the regulating fluid,

. In the drawing, vlike numeralsyof reference refer to 'the same parts'in each the views.

'ln practice I providea casini! 3, connected ywith an inlet pipe-1, and with a iiushinfz pipe 5.

As' shown, the casing 3, is made upA of three parts: 6, 7, and 8, secured together in any desired manner.

Between the parts 46 and 7 mounted a diaphragm 9, secured on a shaft'10, by

means Vot clamping nuts 11, so as -to move therewith. i

Between the parts diaphragm 12, securedon the shaft 10 with may be stated thatpwater is taken up, from the -sea the pump, and forced to Muchltrouble has` been causedy by the clogging-np. of one `oi? the small openings in Hush valve'snow in' use on board ships. lt the object of this 7 and 8, is mounted a Assrenort ro MYER FLUSH VALVE the clamping nuts 13,so to move withsaid sliat. v

I `also provide a passagewayla through said parts, and through lthe two diaphrag'ins, and a 'passa,f feway' 15 through. said parts, and .through the diapliiapms. to the chamberv 16, above the` pipe 5. rThe passageway Y Vl also provide a valve 22,`inountedi-on the shaft 10,1and adapted to form awater# t'ightfconnectionwith the part 23,ofthe part 8.' The shaft 1 0 may be provided with an extension 24, movable in a spiderguide 25, inthe chamber 16. Y

A push button 26 is secured on the outer.`

end of aV shaft 27, on whichvis seeured'a valve 28,' adapted to seat' onthe part29,

to close the passageway 15,',from the cham? ber 18; while guides BO'insure the'vertical movement or" this;l valve whilefprovding tor the tree passage of water kfrom thev chamber 18'to the passageway 15. I In operation, wlienitv is vdesired to flush the urinal, `or toilet, thepush button V26 is shovedV down tok closethefpa'ssageway 1e?A thereby shuttingjoffthe vpressure romthe Y main to the Achamber .18," and the diaphragm -ji's l theL pressure still' remains Vin the chamber `17, the diaphragm 12 will beftoicedV upward by the; pressure on; the -main, as

will. be understood; but the pilot valve 2O,` in lthe partitionl 21, will prevent therapid l, emptying oil? the part ofthe chamber 19l bey low the partition, as 'will be clear.

This l pilotvalve 21 may be regulated so.k as to @if through the'partieon 21, as Wiii aisee@ understood,A Y y y 'gauge the rapidity oit' flow ofthe liquid, or l Then the passageway 14: is closed, ther; water'eontained in the'chamber18 may flow;

past .thefvalve 28, by reason of the open'lu;5

guides 30, and water can also flow into the chamber 16 reason of therliftingr of the valve 22, fromthe seat 23, as this valve is carried upwardby V.the rising of the" dial phragms 9 and 12; and therwater will oon-k tinue to..r flow, past the valve 22, to the iush niet; Y
